A method for making a sludge aggregate concrete includes the steps of collecting and dehydrating sludge, sintering the sludge at a temperature of about 800˜900° C., grinding and sieving the sludge through a screen to obtain sludge ash, forming the sludge ash into an artificial sludge aggregate by mixing the sludge ash with an inorganic binder and water followed by granularizing, and mixing the artificial sludge aggregate with an inorganic binder and water to form the sludge aggregate concrete product.

A toy rocking horse cart with forward and backward controls for children's entertainment consisting of an arc shaped base mounting, chassis, horse body, seat, back resting board, handle, reinforcement battens on the arc shaped base mounting, and other constituent parts, characterized by the fact that conversion of impulses and impetuses produced by the horse rocking on the cart into one-way momentums by the actions of the ratchet wheel sets and check claws therefor so that the cradle will be driven to move forward or else backward, with means to control and to change the direction in which the cart moves. The cart is also provided with braking means to protect the safety of a child rider in getting on or getting off the horse.

A non-volatile memory having a plurality of gate structures, a plurality of charge storage layers and two doped regions is provided. The gate structures are disposed on the substrate and connected in series. The charge storage layers are disposed between every two neighboring gate structures respectively. The gate structures and the charge storage layers form a memory cell column. The two doped regions are disposed in the substrate at both sides of the memory cell column.

A method of fabricating a non-volatile memory is provided. A substrate having a memory cell area and a peripheral circuit area is provided. A plurality of device isolation structures is formed in the substrate. A tunneling dielectric layer is formed on the substrate in the memory cell area and a gate oxide layer is formed on the substrate in the peripheral circuit area. A first conductive layer is formed on the substrate to cover the memory cell area and the peripheral circuit area. The first conductive layer in the memory cell area is patterned. A composite dielectric layer is formed on the substrate. The composite dielectric layer in the peripheral circuit area is removed. A second conductive layer is formed on the substrate to cover the memory cell area and the peripheral circuit area.

A sprayer nozzle includes a housing having a center bore to receive water, and a rotor having a center hole to receive a pivot shaft which may rotatably secure the rotor to the housing. The pivot shaft is offset from the center bore of the housing, and the rotor includes a number of passages disposed around the center hole of the rotor, and arranged to be selectively aligned with the center bore of the housing when the rotor is rotated relative to the housing, to allow the water from the center bore of the housing to selectively flow out through either of the passages of the rotor, and to form different water spraying patterns.
